To all 'whom t 'may concern.

' Be it known that l, CLARENCE H. ALLI- soN, a citizen of the -lllnited States, residing at Chicago, in the county'of Cook and-State of llllinois, have invented new and useful llmprovements in Liquid-Fuel Burners, of which the following is a specification.

This invention relates toliquid fuel burners in which the fuel is burned in an open pan or'tray, and it is the object of the invention to provide in a burner of this kind a novel and improved means for supplying and controlling the air to the burnin fuel. 'llfhe invention also has for itsl obJect to provide a novel improved vburner" nozzle, with a means for draining the burner pan of vvany excess fuel which 'thereinto l f rllhe objects stated are attained by means of va combination and arrangement ofparts to be hereinafter described and claimed, and in order that the same may be better understood, reference is had to the accompanying drawing forming a part of this specification. .'f v' ln the drawing:

Figure 1 is'a central longitudinal section of the burner', and

lFig. 2 is a plan view thereof.

Referring specifically to the drawing, 5

denotes an open pan or tray which is formed 'liti' integral with a base plate 6 from whichv latter it depends. The pan is frusto-conical in shape and'of suitable depth for the purpose for which it is designed,v and from itsv ottom, at the center thereof, rises a hollow conical member A7 which' externally stepped, as shown at 8. The fuel-delivery; pipe 9 passes upward througlrthe part and opens through the apex thereof to d1s charge into the pan 5. The fuel runs down the stepped side of the part 7 and 'when a sulicient quantity is received in thenpan, the burner is started by ignitmg the o1l 1n the pan. By thestepped contour of the part 7, the flames upon. striking back thereon will be deflected sidewise and upward. y

Un opposite sides of the pan 5, the base plate 6 has ar-in1et openings 10, and above ernennen n. antisera, or criticano, mentors. v

and the part 7,

may he delivered the pan, an arched air tube 11 rises from the base plate. This arch straddles the pan 5 and the two legs of the arch seat o ver the openings 10 so thatv the air may pass lnto the arch. Un the inner sides of the legs of the arch, close to the base plate .and across the span vunder the arc and y that an'abunclant supply above the pan, so

to control the air supply.

the openings 12 a tllll' hlt -. 6 are air-outlet openings 12 which face each of air for the burning` fuel in the pan is v provided. The air supply is lreadily con' trolled by the dampers 13 accordinglto the size of the llame." The top of the 'arch gets intensely hot when the burner is in faction, which tends to draw air into the arch from helowthro'ugh the openings 10, andthe air is forcibly discharged through' the outlets 12, resulting in a complete fuell mixturewhich burns with an intense darne.-

Any excess oil delivered to the panh isv1 t into the pan through the side of thev part near the hase thereof. f An asbestos mat 15 is provided to serve taken care of by a drain pipe 1t opening a marginal insulatonagainst air rlsin between the edges of the base plate hand the walls of the fire bor 161in which the burner is mounted, it being understood that it is supported on the grate 17 so in the structure of the stove' are necessary4 for the installation of the burner.

ll claim:

plate having air-inletopenings, an arched air tube rising from the base plate and hav ing its ends in open communication with the airinlet openings, said 4tube-having opposite depending from the base plate and positioned beneath lthe arch, and a burner nozzle rising from the bottom ofthe pan' and discharging into` the space under the arch.
